Clarification of boundary_conditions() example

[dieterjansen]

Thank you for your work on pyhht.

I have been working with the code and do not understand some results I am seeing.

When working through the boundary_conditions() example I got:

>>> from pyhht.utils import boundary_conditions
>>> import numpy as np
>>> signal = np.array([-1, 1, -1, 1, -1])
>>> tmin, tmax, vmin, vmax = boundary_conditions(signal, np.arange(5))
>>> tmin
array([-2,  2,  6])
>>> tmax
array([-3, -1,  1,  3,  5,  7])
>>> vmin
array([-1, -1, -1])
>>> vmax
array([1, 1, 1, 1, 1, 1])

Which agrees with your example.

I would have thought that tmin should be [-2, 0, 2, 4, 6] and vmin should be [-1, -1, -1, -1, -1] - am I misunderstanding?

Hi @dieterjansen

I'm sorry I couldn't look at this all this time, and thanks for pointing this out. Indeed, this does not make sense. I'll try to find out why I wrote that example, and see how we can fix it.

Thanks Jaidev – that would be great. I’m sorry I didn’t have the skills to suggest a resolution. Cheers, Dieter.
